43631481 ÷ 946 
We're looking to find how many times 946 goes into 43631481.

Step 1:
The number 946 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 946

Advancing to step 2:
946 can be fit into 43 0 times, resulting in a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Take the next digit (6) from the dividend and append it to 43, then repeat: 436 / 946

Moving on to step 3:
946 can be fit into 436 0 times, resulting in a remainder of 436.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 436 and we're left with 436.
Take the next digit (3) from the dividend and append it to 436, then repeat: 4363 / 946

Advancing to step 4:
946 goes into 4363 4 times with a remainder of 579.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 3784 from 4363 and we're left with 579.
Append the next digit (1) from the dividend to 579 and continue with: 5791 / 946

On to step 5:
5791 divided by 946 is 6 with a remainder of 115.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
Deduct 5676 from 5791 and we're left with 115.
Bring next digit (4) of the dividend behind the 115 and repeat the process: 1154 / 946

Going ahead to step 6:
If we divide 1154 by 946, we get 1 and a remainder of 208.
Put 1 as the next digit of the answer. 
Result so far: 461.0
Subtracting 946 from 1154 leaves us with 208.
Append the next digit (8) from the dividend to 208 and continue with: 2088 / 946

Going ahead to step 7:
When dividing 2088 by 946, we get 2 with a remainder of 196.
Write down 2 as next digit of the result. 
Result so far: 4612.0
Deduct 1892 from 2088 and we're left with 196.
Bring next digit (1) of the dividend behind the 196 and repeat the process: 1961 / 946

Moving on to step 8:
When dividing 1961 by 946, we get 2 with a remainder of 69.
Record the quotient 2 as the next digit in the result. 
Result so far: 46122.0
Subtracting 1892 from 1961 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 9:
If we divide 690 by 946, we get 0 and a remainder of 690.
The number 0 becomes the next digit in our result. 
Result so far: 46122.0
Subtracting 0 from 690 leaves us with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Let's proceed to step 10:
946 goes into 6900 7 times with a remainder of 278.
Record the quotient 7 as the next digit in the result. 
Result so far: 46122.07
If we subtract 6622 from 6900, we get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Going ahead to step 11:
2780 divided by 946 is 2 with a remainder of 888.
Record the quotient 2 as the next digit in the result. 
Result so far: 46122.072
If we take 1892 away from 2780, we end up with 888.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8880, and continue the process.

Advancing to step 12:
8880 divided by 946 is 9 with a remainder of 366.
Put 9 as the next digit of the answer. 
Result so far: 46122.0729
Subtract 8514 from 8880 to get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Going ahead to step 13:
The number 946 fits into 3660 3 times, leaving a remainder of 822.
Put 3 as the next digit of the answer. 
Result so far: 46122.07293
The remainder is 822 after subtracting 2838 from 3660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8220, and continue the process.

On to step 14:
8220 divided by 946 is 8 with a remainder of 652.
Use 8 as the next digit of our solution. 
Result so far: 46122.072938
Subtracting 7568 from 8220 leaves us with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Moving on to step 15:
946 goes into 6520 6 times with a remainder of 844.
The number 6 becomes the next digit in our result. 
Result so far: 46122.0729386
If we take 5676 away from 6520, we end up with 844.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8440, and continue the process.

Step 16:
946 goes into 8440 8 times with a remainder of 872.
The number 8 becomes the next digit in our result. 
Result so far: 46122.07293868
Subtracting 7568 from 8440 leaves us with 872.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8720, and continue the process.

Our division results in 46122.07293868 with a remaining 8.72e-07.
